Viatores

"It occurs to me that when he says everything is going to change, he means everything: in all five worlds."

Wyn is a Viatores, a Crosser between the five worlds. Armed with her temper, her dragon and her greatest ally, Drey, she jumps from world to world, carrying out Viatores duties. When the balance of power on Steelworld -- a land of medieval society --makes an alarming shift, Wyn is forced to abandon all she knows as she embarks on a death quest that could save all five worlds--or condemn them.

Drey is at a loss. Wyn is his best friend and partner in crime, and has always been his only family. As they're forced to part ways, Drey finds himself on Glassworld, the most futuristic of the five worlds , home to the last painful remnants of his family. Drey's history has always beena question mark, but as answers begin to appear, time begins to run out.

As Wyn and Drey discover a plaguing darkness among the five worlds, they find more about themselves than they bargained for--and what is quite possibly the end of them all.
